Abstract: A cell-growing system may include a cell-growing container, a pump for controlling the pressure of the chamber of the container, a filter for maintaining the chamber sterilized, a flow control regulator for controlling the substance supplied to the cell-growing container. The cell-growing container may include an internal structure that takes the form of a reticulated structure to increase the surface area for growing cells. The cell-growing system may be used to perform cycles of cell expansion and harvest. The cell-growing system may be maintained as a closed and sterilized system through the cycles. In harvesting, a first subset of the cells can be disassociated from the cell culture while a second subset remains. The disassociated cells may be discharged to a collection container while maintaining the system closed to an external environment. The remaining cells may be used as seeds to proliferate more cells in the next cycle.

Abstract: A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising an elongated back panel from which a plurality of flashing tabs extend outward. The flashing tabs are disposed at an angle to the axis and in substantially parallel planes to one another. During use, the elongated back panel is disposed against and coupled to the wall at the intersection, and shingles are then placed along the flashing tabs during the roofing process. The flashing strip may also include a ledge and/or a decorative molding above the flashing tabs. The flashing strips may be placed end to end to form a continuous flashing strip that may be installed before the placement of siding or the like on the wall. The siding may be installed by positioning the siding against the ledge before or after placement of the shingles.
